Hello,
I am trying to install NAMD 2.6 on a CRAY XD1 machine running with AMD opteron 64-bit 2.4 GHz processor. The configuration consists of 6 nodes with 4 processors/node in a single chassis. I have been able to install the 'net-linux' form by compiling the source code. To get a better performance I am trying to install the 'mpi-linux' version of NAMD. I am having some issues doing that and I have tried looking at the archive, but couldn't find a similar issue faced by other AMD 64 queries.
I am getting stuck in testing the charmrun after building it. I have tried the following to build charm:
./build charm++ mpi-linux-amd64
./build charm++ mpi-linux-amd64 -O -DCMK_OPTIMIZE=1
In both cases, when i try to run the 'megatest':
==========================================
cd mpi-linux-amd64/tests/charm++/megatest/
make pgm
./charmrun ++local +p4 ./pgm
==========================================
I run into the following problem:
===========================================
./charmrun ++local +p4 ./pgm
Running on 4 processors: ++local ./pgm
Unrecognized argument ++local ignored.
Without hostfile option, hostnames must be specified on command line.
Usage: mpirun_rsh -np N [-debug] [-paramfile pfile] [-show] [-tv] [-xterm]
(-hostfile hfile | h1 h2 ... hN)
<progname> [options...]
Where:
np => specify the number of processes
debug => run each process under the control of gdb
paramfile => file containing the run-time MRICH parameters
show => show the commands but don't execute them
tv => run each process under the control of totalview
xterm => run the remote processes under xterm
hostfile => name of the file contining the hosts on which
to run the job, one per line
or
h1 h2 ... => names of the hosts on which to run the job
progname => name of the MPI binary
options => arguments for the MPI binary
======================================================
are there any solutions to this?
Thanks
Vani
